Description
本発明は、液化ガスまたは可溶性圧縮ガスを使用するエアゾール式製品のアクチュエータ倒立定量噴射機構に関する。 The present invention relates to an actuator inverted quantitative injection mechanism for an aerosol type product using a liquefied gas or a soluble compressed gas.
このアクチュエータ倒立定量噴射機構は、エアゾール式製品の噴射操作に基づき、先ずアクチュエータ内部の定量室流出弁が閉じてステムの定量室流入弁が開くことにより、定量室空間域に容器本体内容物(ハウジング内容物)が流入して貯留され、その後、ステムが静止モード位置へ復帰して定量室流入弁が閉じることにより、定量室の貯留内容物が、その液化ガスや可溶性圧縮ガスの作用(または弾性部材の作用)によって開状態となった定量室流出弁から外部空間域へと噴射されるタイプのものである。 This actuator inverted fixed quantity injection mechanism is based on the injection operation of the aerosol type product. First, the fixed quantity chamber outflow valve inside the actuator is closed and the fixed quantity chamber inflow valve of the stem is opened. The contents are inflowed and stored, and then the stem returns to the stationary mode position and the metering chamber inflow valve closes, so that the contents of the metering chamber are affected by the action of liquefied gas and soluble compressed gas (or elasticity) The metering chamber outflow valve, which is opened by the action of the member), is of a type that is injected into the external space region.
特に、倒立定量噴射用操作部材として、頭皮などの噴射対象部に押付けられる剣山式の複数の凸状部などを形成した縦方向押付け操作部材に加えて、当該縦方向押付け操作部材をその押付け方向に駆動するための横方向押圧操作部材を設けることにより、倒立定量噴射操作上の利便性を確保したアクチュエータ倒立定量噴射機構に関する。 In particular, in addition to the vertical pressing operation member formed with a plurality of sword-shaped convex portions that are pressed against the injection target portion such as the scalp as the inverted quantitative injection operating member, the vertical pressing operation member is in the pressing direction. The present invention relates to an actuator inverted fixed-quantity injection mechanism that secures convenience in the inverted fixed-quantity injection operation by providing a lateral pressing operation member for driving.
本明細書では「アクチュエータ」の語を、エアゾール容器のバルブ作用を呈するステムに取り付けられて内容物を外部空間域に噴射するための作動部の意で用いる。 In this specification, the term “actuator” is used to mean an operating part that is attached to a stem that exhibits the valve action of an aerosol container and injects contents into an external space.
例えば図1〜図5の倒立定量噴射機構において、弁部材5,可動部材6,押付け操作部材7および押圧操作レバー8の全体が「アクチュエータ」に相当する。
For example, in the inverted fixed quantity injection mechanism of FIGS. 1 to 5, the
また、「上下」,「縦」の語をステム,アクチュエータなどの長手方向、すなわち各図の縦方向を示す意で用い、「横」の語をこの「上下」,「縦」に対する直交方向あるいは斜め方向を示す意で用いる。 In addition, the terms “upper and lower” and “vertical” are used to indicate the longitudinal direction of the stem, actuator, etc., that is, the vertical direction of each figure, and the term “horizontal” is the orthogonal direction to this “upper and lower” and “vertical” or Used to indicate an oblique direction.
本件出願人はすでに上記タイプのアクチュエータ定量噴射機構、すなわち定量噴射操作に基づいて先ず定量室流出弁が閉じた状態の定量室に容器本体の内容物を流入させて貯留し、その後、定量室流出弁が開いて定量室の貯留内容物を外部空間域に噴射するタイプのアクチュエータ定量噴射機構を提案している(特許文献1,2参照)。 The applicant of the present invention has already stored the contents of the container body by flowing into the metering chamber with the metering chamber outflow valve closed based on the above-described type of actuator metering mechanism, that is, the metering injection operation. There has been proposed an actuator fixed quantity injection mechanism of a type in which the valve is opened and the stored contents of the fixed quantity chamber are injected into the external space (see Patent Documents 1 and 2).

It consists of structural members.
そして、弁座部22の環状弁座24および操作ボタン本体25の環状弁体26で定量室流出弁を構成している。
The
操作ボタン本体25を押下げていない静止モードの場合、操作ボタン用コイルスプリング23の弾性力により定量室流出弁が開いている。
このときステム21の定量室流入弁(=内容物通過用のステム周面孔部とこれを開閉する周知のステムガスケットとからなる弁)が周知のステム用コイルスプリングの作用により閉じている、ことは勿論である。In the stationary mode in which the
At this time, the metering chamber inflow valve of the stem 21 (= the valve comprising a stem peripheral surface hole for passing the contents and a well-known stem gasket for opening and closing it) is closed by the action of a well-known stem coil spring. Of course.
なお、周知のステム用コイルスプリングおよびステムガスケットは、それぞれ図1〜図5のステム用コイルスプリング10,ステムガスケット11と同様のものである。
The well-known stem coil spring and stem gasket are the same as the
操作ボタン本体25をその静止モードの位置から押下げると、先ず当該ボタン本体のみが操作ボタン用コイルスプリング23の弾性力に抗しながら下動して定量室流出弁が閉じる。
When the
定量室流出弁が閉じた後は、ステム21,弁座部22および操作ボタン本体25が一体となって、すなわち定量室流出弁が閉じたまま下動して定量室流入弁が開き、容器本体の内容物が定量室に入り込んで貯留される。
After the metering chamber outflow valve is closed, the
次に、利用者が操作ボタンの押下げ操作を止めると、ステム21がステム用コイルスプリングの弾性作用により上動して定量室流入弁は閉じ、かつ、操作ボタン本体25が操作ボタン用コイルスプリング23の弾性作用により(弁座部22に対して)上動して定量室流出弁は開く。そのため、定量室の貯留内容物のみが外部空間域に噴射される。
Next, when the user stops the pressing operation of the operation button, the
本件出願人は、以上のアクチュエータ定量噴射機構について更なる考察,検討,試作を重ねた結果、操作ボタン本体付勢用の操作ボタン用コイルスプリングを省略しても、ステムの静止モードへの復帰の際に、定量室の出力弁が定量室内部の液化ガスや可溶性圧縮ガスの圧力で「開」状態になる、すなわち定量室の貯留内容物が外部空間域に確実に噴射されることを検証した。 As a result of further consideration, examination, and trial production of the above-described actuator quantitative injection mechanism, the applicant of the present application can restore the stem to the stationary mode even if the operation button coil spring for urging the operation button body is omitted. In this case, it was verified that the output valve of the metering chamber is in an “open” state due to the pressure of the liquefied gas or soluble compressed gas inside the metering chamber, that is, the contents stored in the metering chamber are reliably injected into the external space. .
特許文献2のアクチュエータ定量噴射機構は、この検証に基づくものであり、操作ボタン用コイルスプリング13を省略した形のアクチュエータ定量噴射機構になっている。
The actuator fixed quantity injection mechanism of
本発明は、本件出願人にかかるこのようなアクチュエータ定量噴射機構の開発のいわば延長線上のものであり、上述の操作ボタン用コイルスプリング23を省略できるかどうかとは別の観点からのアプローチに基づいている。
The present invention is an extension of the development of the actuator quantitative injection mechanism according to the applicant of the present application, and is based on an approach from a viewpoint different from whether or not the above-described
すなわち、頭皮などの噴射対象部位に押付けられる剣山式の縦方向に移動可能な押付け操作部材を備えたアクチュエータ倒立定量噴射機構に、当該縦方向押付け操作部材をその被押付け方向に駆動するための横方向に移動可能な押圧操作部材を付加して、倒立定量噴射操作上の利便性を高めることを目的とする。 That is, an actuator inverted fixed quantity injection mechanism having a sword-mount type vertical movement movable pressing member that is pressed against an injection target site such as the scalp is provided with a lateral force for driving the vertical pressing operation member in the pressed direction. It is an object to add a pressing operation member that can move in the direction to enhance the convenience of the inverted fixed quantity injection operation.
この目的は、操作ボタン用コイルスプリング23を省略した形のアクチュエータ倒立定量噴射機構および、当該操作ボタン用コイルスプリングを設けたままのアクチュエータ倒立定量噴射機構のいずれにも妥当する。
This purpose is applicable to both the actuator inverted fixed quantity injection mechanism in which the operation

本発明は、倒立定量噴射用の操作部材として、頭皮などの噴射対象部に押付けられる剣山式の複数の凸状部などを形成した縦方向に移動可能な押付け操作部材だけではなく、当該縦方向押付け操作部材をその被押付け方向に駆動するための横方向に移動可能な押圧操作部材も用いているので、倒立定量噴射操作上の利便性を確保することができる。 The present invention is not only an operation member for inverted fixed quantity injection, but also a vertical operation unit that is movable not only in the vertical direction, but also in a vertical direction in which a plurality of sword-shaped convex portions that are pressed against an injection target part such as the scalp are formed. Since the pressing operation member that can move in the lateral direction for driving the pressing operation member in the pressed direction is also used, it is possible to ensure convenience in the inverted fixed quantity injection operation.
例えば頭皮への弱い押付け状態(=ステムが十分に倒立上方向に駆動されずに定量室流入弁がいわば開ききっていない状態)でこの倒立定量噴射機構を用いる場合にも、利用者が横方向押圧操作部材を内側に押すことにより、ステムは、頭皮への強い押付け時と同じように定量室流入弁の十全な開状態へと確実に移動する。 For example, even when this inverted quantitative injection mechanism is used in a state where the pressure is weakly pressed against the scalp (= the stem is not driven sufficiently upside down and the metering chamber inflow valve is not fully opened), By pushing the pressing operation member inwardly, the stem is surely moved to the fully opened state of the metering chamber inflow valve in the same manner as when strongly pressing the scalp.
上述したように本発明は、操作ボタン用コイルスプリング23を用いるアクチュエータ倒立定量噴射機構および、当該操作ボタン用コイルスプリングを用いないアクチュエータ倒立定量噴射機構のいずれの場合も対象としている。

図1〜図5のアクチュエータ倒立定量噴射機構の基本的特徴は、
(11)倒立定量噴射用の操作部材として、縦方向に移動可能で、頭皮13などに押付けられる剣山式の複数の凸状部7eを形成した押付け操作部材7のみではなく、
(12)横方向に移動可能で、押付け操作部材7をその被押付け方向に駆動するための押圧操作部材8を併用している、
ことである。The basic features of the actuator inverted quantitative injection mechanism of FIGS.
(11) As an operation member for the inverted fixed quantity injection, not only the
(12) It is movable in the horizontal direction and is used in combination with the
That is.
図1および図2の静止モードでは、通常のエアゾール式製品と同様にステム4がステム用コイルスプリング10の弾性力に基づいて上動し、ステムの横孔部4bはステムガスケット11で閉塞されている。すなわち定量室流入弁は「閉」状態である。
In the stationary mode of FIGS. 1 and 2, the
このとき可動部材6およびこれと一体の押付け操作部材7は、その通路部7bの入口側の円形縁部分7dが弁部材5の中央円錐台状部5aに当接した状態になっている。すなわち定量室流出弁は開状態に設定されている。
At this time, the
また、前回の倒立定量噴射モード(図4参照)における定量室出力弁の開きの程度(=中央円錐台状部5aと円形縁部分7dとの間隔)や、可動部材6の内筒状部6aの内周面と弁部材5の逆スカート部5dとの摩擦力の大きさに応じて、定量室出力弁が開状態の静止モードに設定されることもある。もっともこのときの中央円錐台状部5aと円形縁部分7dとの離間距離は0.1mmほどにすぎない。
Further, the degree of opening of the metering chamber output valve (= interval between the central
なお、上述の操作ボタン用コイルスプリングを用いたアクチュエータ倒立定量噴射機構の静止モードにおいては勿論、定量室流出弁が「開」になっている。 The metering chamber outflow valve is “open” as a matter of course, in the stationary mode of the actuator inverted fixed quantity injection mechanism using the coil spring for operation buttons described above.
図3の定量室流入モードは、利用者が容器本体1を把持しながら押付け操作部材7の突状部7eを頭皮13に押し付けて、当該容器本体およびこれと一体の肩カバー9がステム4,弁部材5,可動部材6および押付け操作部材7に対して倒立時下方に移動した状態を示している。
3, the user presses the protruding
図3の定量室流入モードを相対的にみれば、ステム4,弁部材5,可動部材6および押付け操作部材7が容器本体1に対して倒立時上方に移動しているともいえる。
From the relative view of the metering chamber inflow mode of FIG. 3, it can be said that the
図4の定量室流入モードは、利用者が押圧操作レバー8の操作面8aを図示矢印のように内側へと押圧して、これにともなう当該押圧操作レバーの直線状腕部8cそれぞれの斜面8dと、可動部材6の従動直方体状凸部6eそれぞれの倒立時下縁部分6fとのカム作用により、当該可動部材およびこれと一体の押付け操作部材7が倒立時上方に移動した状態を示している。
In the metering chamber inflow mode of FIG. 4, the user presses the
図3および図4の定量室流入モードにおけるアクチュエータ側の動きを、容器本体1を基準にした相対的な位置関係でみると、いずれも、
(21)可動部材6と押付け操作部材7との一体物が倒立時上方向へと移動し、
(22)この移動にともなって、上述のごとくそれまで仮に開状態であった定量室流出弁も、その押付け操作部材7の円形縁部分7dが弁部材5の中央円錐台状部5aに確実に密接して、閉状態に設定され、
(23)その後は、可動部材6,押付け操作部材7とともに、弁部材5およびこれと一体のステム4が閉状態の定量室流出弁を介して倒立時上方に移動し、
(24)このステム4の移動により、横孔部4bの入口側に設定されたステムガスケット11の内側が変形して両者間のシール状態が解除され、すなわちそれまで閉じていた定量室流入弁が開状態に移行する。When the movement on the actuator side in the metering chamber inflow mode of FIGS. 3 and 4 is seen in the relative positional relationship with respect to the container body 1,
(21) The integrated member of the
(22) Along with this movement, the metering chamber outflow valve that had been in the open state as described above also has the
(23) Thereafter, together with the
(24) Due to the movement of the
すなわち図3および図4の定量室流入モードでは、定量室流入弁が開き、定量室流出弁が閉じた状態に移行している。 That is, in the metering chamber inflow mode of FIGS. 3 and 4, the metering chamber inflow valve is opened and the metering chamber outflow valve is closed.
そのため、図3および図4の倒立状態の容器本体1の内容物および噴射用液化ガスが、それぞれ矢印Bで示すように「ハウジング3の切欠状部3a−ハウジング3の内周面とステム4の外周面との環状空間域−ステム4の横孔部4b−ステム4の内側通路部4a−弁部材5の内部空間域−弁部材5の孔部5c」を経て、定量室Aに流入し、貯留される。
Therefore, the contents of the container body 1 in an inverted state and the liquefied gas for injection shown in FIGS. 3 and 4 are “notched
なお、上記(22)の「それまで仮に開状態であった定量室流出弁も、その押付け操作部材7の円形縁部分7dが弁部材5の中央円錐台状部5aに確実に密接して、」となるのは、押付け操作部材7およびこれと一体の可動部材6が、弁部材5に対して、内筒状部6aの内周面と逆スカート部5dとの摩擦力に抗する形で相対移動するからである。
In addition, in the above-described (22) “quantitative chamber outflow valve that was temporarily open, the
図5の倒立定量噴射モードは、図3の押付け操作部材7の頭皮13に対する押付け操作または図4の押圧操作レバー8の容器内側への押圧操作が解除されて定量室Aの貯留内容物が外部空間域に噴射されるモード、すなわち定量室流入弁が閉じて定量室出力弁が開いた状態を示している。
In the inverted quantitative injection mode of FIG. 5, the pressing operation of the
なお、押付け操作部材7の押付け操作および押圧操作レバー8の押圧操作がともに行われている場合には、これら双方の操作がともに解除された場合にはじめて倒立定量噴射モードへと移行する。
When both the pressing operation of the
図5の倒立定量噴射モードでは、
(31)ステム4およびこれと一体の弁部材5は、ステム用コイルスプリング10の弾性力により下動して図1の静止モード位置に復帰し、その横孔部4bが通常のエアゾール式製品の場合と同じようにステムガスケット11で閉塞され、
(32)可動部材6およびこれと一体の押付け操作部材7は、弁部材5(ステム4)に対し、それぞれの自重や、定量室Aの貯留内容物の下方向圧力(液化ガスの圧力)に基づいて下動することにより、当該押付け操作部材の円形縁部分7dが当該弁部材の中央円錐台状部5aから離間し、
(33)また、可動部材6および押付け操作部材7の弁部材5に対する最下動位置は、当該可動部材の段部6dが当該弁部材の環状鍔部5eと当接した位置に特定される。In the inverted fixed quantity injection mode of FIG.

(33) Further, the lowest position of the
このように定量室流入弁が閉じ、定量室出力弁が開いた状態の倒立定量噴射モードに移行すると、定量室Aの貯留内容物は、液化ガスの作用で、図5の矢印Cで示すように「弁部材5の中央円錐台状部5aと押付け操作部材7の円形縁部分7dとの隙間空間域−通路部7b−複数の孔部7c」を経て外部空間域に噴射される。
When the metering chamber inflow valve is closed and the metering chamber output valve is open, the stored content in the metering chamber A is moved by the liquefied gas as indicated by an arrow C in FIG. Then, it is injected into the external space region through “the gap space region between the central
図5の倒立使用時において、可動部材6および押付け操作部材7が、定量室Aの内容物の圧力作用(液化ガスの圧力作用)により弁部材5に対して下動するのは、当該押付け操作部材の定量室確定天井面部分に図示下方向の圧力が作用し、また、可動部材6および押付け操作部材7の自重が下方向に作用するからである。
In the inverted use of FIG. 5, the
このように図示のアクチュエータ倒立定量噴射機構では、定量室流出弁を開くための上述の操作ボタン用コイルスプリング23を設けることなしに、当該定量室の貯留内容物の圧力自体などにより定量室流出弁を「開」状態に設定している。
Thus, in the illustrated actuator inverted quantitative injection mechanism, the quantitative chamber outflow valve is not provided by the above-described operation
したがって、この操作ボタン用コイルスプリングの分だけ、定量噴射機構の部品点数が減るとともに、押付け操作部材7や押圧操作レバー8への定量室流入モード設定操作が軽いものとなる。
Accordingly, the number of parts of the quantitative injection mechanism is reduced by the amount of the operation button coil spring, and the quantitative chamber inflow mode setting operation to the
上述の定量室流入モードおよび倒立定量噴射モードの各動作が担保されるためには、定量室Aの貯留内容物の圧力に関し、
(41)定量室流入モードにおける、ステム4および弁部材5に対して倒立時上方向に作用する当該圧力の荷重が、ステム用コイルスプリング8の倒立時下方向への付勢力(例えば2.0kgf)よりも小さく、
(42)倒立定量噴射モードにおける、可動部材6および押付け操作部材7に対して倒立時下方向に作用する当該圧力の荷重と、当該可動部材および当該押付け操作部材の自重との合力が、逆スカート部5dと下筒状部6aの内周面との間の倒立時上方向への摩擦力よりも大きい、
ことが必要である。In order to secure each operation of the above-mentioned fixed-quantity chamber inflow mode and inverted fixed-quantity injection mode,
(41) In the metering chamber inflow mode, the load of the pressure acting on the
(42) In the inverted fixed quantity injection mode, the resultant force of the pressure load acting on the
It is necessary.
これは、例えば上記(41)の要件を満足しないと、上記貯留内容物の圧力の作用で弁部材5と押付け操作部材7とが相対的に離れる方向に移動して定量室流出弁が開き、通常の連続噴射状態のようになり得るからである。
For example, if the requirement (41) is not satisfied, the metering chamber outflow valve is opened by moving the
以上の定量室Aの貯留内容物の圧力に基づく上記荷重は例えば(0.3〜1.5)kgfに設定する。ただ、この数値は単なる一例であって、上記(41),(42)の要件を満たす任意の値に設定し得る。 The load based on the pressure of the stored contents in the quantification chamber A is set to (0.3 to 1.5) kgf, for example. However, this numerical value is merely an example, and can be set to any value that satisfies the requirements (41) and (42).
